Roll clouds near Meekathara WA, March 2016

Took that pic about a month ago around Meekatharra area. (ie, around March 25th 2016)
Photo it has been taken from FL370 northbound
I was flying towards the Pilbara on Y31 to Newman. That route is practically north bound and the picture is on the right end side 90 degrees to the route.

I would probably say direction east west more or less.
